Ubushakashatsi duherutse gukora, ahahinzwe iyi mbuto nshya, habonetse Toni hagati ya 34-36 kuri Hegitari, mu gihe ku mbuto y’ibirayi isanzwe heze Toni 2-3 kuri Hegitari, aho hombi nta muti wabaga watewemo, ariko imirima yombi iri hamwe kandi ifite imiterere imwe”.

Ubushakashatsi rero bugira inzira yabwo kugira ngo bube budadiye, buzasohoke bwizewe. Ni ukuvuga ko tugomba kubanza kumenya niba iyi mbuto ikunze mu Majyepfo, mu Majyaruguru n’ahandi niba na ho ari ko bimeze, tukareba no ku bihembwe by’ihinga, bityo imbuto ikazasohoka tuzi neza ko uyihinze agomba kweza neza”.

Abafite impungenge ku biciro by’iyo mbuto nshya bahumure, izajya igurishwa kimwe n’izisanzwe, kandi nibanahinga izerera igihe kimwe n’izisanzwe, ni ukuvuga niba ari amezi atatu cyangwa atatu n’igice ku mbuto zisanzwe, no kuri iyi nshya ni kimwe”.

Akomeza avuga ko umuhinzi uzatera izi mbuto azabyungukiramo cyane, kuko azashora bike agasarura byinshi.
